A potential to be tapped

The Rexroth Off-Highway Technology Demonstrator, a six by three meters life-size display, visualizes the company’s main system developments at its bauma China booth.

System know-how is essential for further breakthroughs in technology for mobile equipment

An eye-catching, six by three meters life-size technology demonstrator (TeD) showcases the latest developments by Bosch Rexroth such as the HSS Hydraulic Start Stop for compact construction equipment, the HVT power-split travel drive from the joint-venture Dana Rexroth Transmission Systems, and the HTA Hydraulic Traction Assistant for trucks on difficult terrain.

“Our ‘TeD’ illustrates just how much untapped potential there is when looking at a machine as a system rather than as the sum of isolated functions or individual components”, says Peter Dschida, Senior Vice President Sales Mobile Applications at Bosch Rexroth. Bringing together and managing the complex interplay between diesel control, cooling, exhaust gas after-treatment, implement hydraulics, travel drive and electric or hydraulic hybrid technologies is a challenge, as well as the key for further advancements of mobile equipment. Dschida: “And here Bosch Rexroth, as part of the Bosch Group, has a competitive edge to create intelligent and innovative solutions in terms of energy efficiency, cost-effectiveness, comfort and usability.”

Dschida expects the use of modern electronics to increase in construction equipment and other mobile working machines, as electronics will bring together the various functional modules and systems. “It would be a mistake, tough, to neglect the component level, because the system and function levels of modern machines must build on best-in-class components”, says Dschida. Consequently, next to advanced system solutions Rexroth also presents numerous innovations on a component level.

Solutions for concrete machines [PI 088-14]
As China is one of the leading markets for concrete machinery, requirements in terms of energy efficiency and cost control are gaining momentum. At this year’s bauma China, Rexroth presents a number of answers including the state-of-the-art series 40 of the A4VG axial piston variable pump for a higher pressure level up to 450 bar in concrete pumps. The Rexroth DHC Diesel Hydraulic Control for concrete mixers offers gains in energy efficiency as well as noise reductions. DHC for concrete mixers relies on reliable and cost-effective components such as the new series 34 of the proven Rexroth A4VTG pump for drum drives, which the company also introduces at the fair in Shanghai.

High performance flow sharing for mini excavators [PI 090-14]
At bauma China 2014 Rexroth presents the new size 15 of its RS valve platform. The new RS control block platform is the successor of the Rexroth SX series, which pioneered the LUDV technology in the mini excavator market. Compared to the successful SX14 valve, the new Rexroth RS15 features an increased flow capacity of 30 percent, while significantly reducing energy wasting pressure losses. The maximum operating pressure is 350 bar. With these specifications, it covers the requirements of excavators from 9 to 12 tons.

Compactness and higher power density with new Rexroth motors [PI 091-14]
More power and compactness: the new Rexroth A2FM 70 series bent-axis hydraulic motors are up to 26% shorter, and are remarkable for their high power density. At the same time, Rexroth has added two extra pressure levels to the new series 70 to cover the pressure range from 350 up to 500 bar. The new A2FM 70 series is now suitable for the more cost-sensitive low-pressure applications as well as for heavy-duty applications with highest pressure demands.

New BODAS controllers and sensors from Rexroth [PI 092-14]
Rexroth is adding a new control unit and two new sensors to its mobile electronics modular BODAS portfolio. The “BOsch Rexroth Design and Application System” is a finely scalable system including all hardware components, application software and engineering tools required for the electronic control of mobile working machines. The new BODAS controller RC10-10 series 31 from Rexroth provides even greater support to OEMs in acquiring the certification of machine safety. The new Rexroth PR4 pressure sensor sets standards in the area of sensor technology thanks to its accuracy as well as its high load capacity, for example when dealing with pressure peaks and thermal shock. The new five-axis inertial sensor AC1 simultaneously senses three times acceleration and two times rotational speed. It is thus suitable for several application options.

A28VO double-pump new size 130 for standard excavators [PI 093-14]
With the shortest double pump available on the market for implement hydraulics, Rexroth creates more space for the diesel engine and the exhaust gas treatment components in excavators. The new size 130 of the A28VO Axial Piston Variable Double Pump from Rexroth is built up to 20 percent shorter than is conventional. Thanks to the increase in total efficiency of three to five percent and to the 20 bar increase in permissible nominal pressure and maximum pressure, it generates the same work performance while requiring less energy. That reduces the diesel consumption of excavators, lowering the operating costs.


Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, Factory Automation, and Renewable Energies to develop innovative components as well as tailored system solutions and services. Bosch Rexroth offers its customers hydraulics, electric drives and controls, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, roughly 36,700 associates generated sales revenue of approximately 5.7 billion euros in 2013.

Intelligent hydraulics for increased availability

Connected hydraulics increase the availability of machinery and plants through condition monitoring and predictive maintenance. For this purpose, Rexroth offers scalable solutions, from individual units with local evaluation to the complete, cloud-based monitoring of large plants. Sensors measure all relevant operating conditions and software detects wear before it leads to failure. Retrofitting kits also economically integrate already installed plants into these concepts.
